The First Dog made his debut on the South Lawn of the White House Tuesday afternoon before at least 60 members of the press.
"Here he is," President Obama said as he and his family walked out of the house.
"I've finally got a friend; it took some time," the president joked at one point when a reporter made a reference to President Harry Truman's famous advice that "if you want a friend in Washington, get a dog."
Bo Obama, a Portuguese water dog, frolicked with his new owners before a herd of cameras and scribes, before the president, first lady and the Obama daughters took him for a walk down the hill toward the fountain and the first lady's new garden.
"He's a star; he's got star quality," Obama said. "He's a rock star."
The long-awaited and much-talked-about arrival of Bo, perhaps the most famous dog in America, fulfilled a promise Obama made to his daughters during the election.
"That's a good-looking dog," the president added. "The only concern we have is apparently Portuguese water dogs like tomatoes. Michelle's garden is in danger."
